According to Lemoine, the incoherence of the dream-images is the sole essential characteristic of the dream. Maury agrees with him (Le Sommeil, p. 163): “Il n’y a pas des reves absolument raisonnables et qui ne contiennent quelque incoherence, quelque absurdite.”26 26 There are no dreams which are absolutely reasonable which do not contain some incoherence, some absurdity.
